Bismuth oxycarbonate

?????????? C??? ??, ??, ??

??? ??

White Fine powder

??? ??

White powder; density 6.86 g/cm3; insoluble in water and alcohol; soluble in mineral acids.

??

Bismuth subcarbonate [(BiO)2CO3] is used to make other bismuth compounds, cosmetics, enamel, and ceramic glazes. Its major use is as an opaque substance placed in the digestive tract to show up on X-rays.

?? ??

Bismuth oxycarbonate is prepared by adding sodium carbonate to a suspension of bismuth subnitrate in water.
BiONO3 + Na2CO3 → (BiO)2CO3 + 2NaNO3
(BiO)2CO3also may be prepared by adding ammonium carbonate to a solution of bismuth salt. The nature of the product in the preparative processes depends on the nature of the subnitrate or the bismuth salt used, the amount of water and the temperature.
